how to connect between 2 or more apps with high performance

Question

I have different api's writed in nodejs and python. what is a FAST way to call methods/events and transfer files between then?

is curl really fast for high volume of requests? or is there another method to better performance?

maybe socket.io for a permanent connection? or websockets?

Answer 1

Have a look at Redis and its pub/sub features.

Redis does have a client for both Node.js and Python, so it should offer exactly the functionality you require.
